Vim control lines were re-introduced or not entirely cleaned up.
This nukes them again.
Removing from the rest of js, caps, chrome, config, devtools, docshell,
image, intl. More to come.
Since these are just interpreted comments, there's 0 impact on actual code.
This removes all lines that match /* vim: set(.*)tw=80: */ with S&R -- there are
a few others scattered around which will be removed manually in a second part.
This creates a number of stubs and leaves some surrounding code that may be irrelevant (eg. recorded time stamps, status variables).
Stub resolution/removal should be a follow-up to this.
